Pipeline broken due to TLS error

SSL certificate problem: unable to get local issuer certificate

This might relate to the CA certificates in one of the container images, tried to update them but didn't help.

Weirdly this happens when connecting to Github and it used to work fine, then it started occasionally breaking, now it seems all broken. Coincidently Github is currently moving to a new certificate after using the same one for 3 years. Perhaps this is signed by an intermediate not in the docker image or some other weird thing might be happening.

As usual, Stack Overflow advises us to just disable TLS altogether and users are reporting stuff works again after doing so.. #fml
